I don’t understand why you’d be rolling your eyes at those comments, as they’re completely true.
The Supreme Court of Canada’s function, per the Parliament of Canada that created it, is to make determinations as to whether provisions of laws brought before it are consistent with the Constitution Acts, 1867–1982. When laws are inconsistent with the constitution, those laws are of ‘no force or effect’ (that’s why, for example, abortions laws remain on the books—they were never repealed, but are of ‘no force or effect’ because they are inconsistent with the Charter). It is the duty of the Supreme Court to ensure that decisions uphold (1) the Canadian Charter of Rights and Freedoms, (2) other sections of the Constitution Acts, 1867–1982, and (3) written laws, in that order.
On the other hand, it is solely and exclusively the duty of the Honourable the Senate of Canada, and the House of Commons, to pass amendments to legislation or to the constitution to re-assert the wishes of the majority, should the Supreme Court make a decision that strikes down a more ‘popular’ law. The Supreme Court and the legislature perform complementary functions to one another, but let us be clear that the Supreme Court has never ‘created’ or ‘changed’ the law, only struck down laws that were inconsistent with the supreme law (the constitution), as is the Supreme Court’s primary function.
